Math - SAT planning for the advanced student in Accelerated Learner Board Posted February 26, 2016 Hello! I am looking ahead at our math studies. We are loving Saxon Math and I believe we might be able to finish Calculus by 13 or 14 years old. My question is whether that is wise given the SATs are taken at age 16. There's a lot of time to forget things in that period. I might not want to try the SATs early because of the verbal section. Thanks!
